The word "Angus" associated with a beef product can mean just about anything since the word is not trademarked.  It's a free-for-all in that respect.  The original "Certified Angus Beef" has to come from an animal that is first 51% contiguous black hide and then meet these specs:  http://www.certifiedangusbeef.com/brand/specs.php

I think it's a bit crazy to say that all beef should be advertised the same and never admit that there are differences.  A person with no knowledge about differences in grades of beef could purchase a Select steak and have a bad experience.  If not educated to the fact that he/she has purchased a cheaper and lower grade "Select" then they go away possibly saying "I don't like beef" because it didn't possibly have the flavor and juciness of a higher grade.  If all Americans could eat something like Certified Angus Beef and then understand why it tastes superior and why it costs more then we'd not have as big a beef demand problem as what we are facing today.  They might happily pay more to enjoy that occassional steak dinner.  Just might not afford to do it everyday.  Hamburger is still cheap enough for a whole lot of folks to enjoy on a more regular basis.  Yes, I know I'm biased toward higher quality and not apologizing for it.  McDonald's is a great customer of the American Rancher, by the way.  We should love that company even if we don't all love to eat there.  Lots of people do, thank goodness.
